Is your computer using way too little graphics power?
Is your computer using way too little graphics power?
According to geofelt, your main problem is that your CPU only has one thread at a time and this is needed for most of the games. To check this, you can run a GPU-focused test called Furmark on both computers you want to compare and see if they give the same score. If they do give the same score, then to fix your issue, it means you should replace your CPU with one that has more power.
